The first episode puzzled me a bit as the story progressed pretty slow. There is not much excitement or information I can gather. Well, some series are like that so I gave it the benefit of the doubt since the rating of this show is rather respectful.
At episode 4 I have grown rather restless as it seems the story is going nowhere. After the 5th episode I totally abandoned it.
The art is good but there story is not catchy enough to keep me out of stamina. This is one of the few anime which I failed to enjoy and eventually abandon mid-way. It perhaps appeals to people who fancies long slow plots and lots of conversations.
To be fair, I do not know what happens beyond episode 6.
